The core dynamos of Mars and the Moon have distinctly different histories. Mars had no core dynamo at the end of accretion. It took ~100 Myr for the core to create a strong dynamo that magnetized the martian crust. Giant impacts during 4.2-4.0 Ga crippled the core dynamo intermittently, until a thic...
